Nobody at Sony is recommending that you recreate iconic tracks from Nintendo's Mario Kart in the upcoming PlayStation 3 game LittleBigPlanet Karting. But what do you think is going to happen when you let gamers into a beta of a kart-racing game that has a very malleable track editor?

You get Mario Kart tracks in your LittleBigPlanet kart-racer, of course. We've got four of them in the video, via the game's just-concluded beta. DK Mountain and Bowser's Castle are the stand-outs. And they were only made in the limited one-month beta. When this game comes out in the fall, you can expect much better Mario Kart on Sony's console. Nothing official, of course.
